GAS-BURN ER.

SPECIFICATION forming part of Letters Patent No. 742,594, dated October 27, 1903. Application filed November 23, 1901. $erial No. 83,374. (No models To all whom it may concern:

Be it known that I, WARREN COLLINS, of Collegepoint, Long Island, in the county of Queens, in the State of New York, have invented new and useful Improvements in Gas- Burners, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to a gas-burner of im- Io proved construction andoperation; and it consists of a base with a small inlet for the gas, a mixing-chamber arranged above the base and formed with a large inlet for the air, and an upper mixing-chamber connected therewith, where the gas and air are further mixed and forced outwardly by passing through a nest of radiating partitions, whereby an intimate mixture of the gas and air is obtained and practically perfect combustion when the mixture is ignited above the gauze top with a hot flame for generating heat and for rendering incandescent the mantle arranged above the flame. In the base are arranged means for regulating the flow of gas and air to be mixed andsimultaneously controlling the amount admitted, also means for regulating a supply of gasfor a pilot-light when the main supply iscut off. A desirable means for supporting the mantle is shown. 0 My invention will be understood by reference to the accompanying drawings, in which the reference-numerals of the specification indicate the same parts in all the figures.

FigureI is an elevation of my burner. Fig.

3 5 II is a vertical section. Fig. III is asection of the base at right angles to Fig. II. Figs. IV, V, and VI are bottom plans and sections illustratin g the regulation of the air-supply. Fig. lV'isasection through thebase and shell,taken above the annular controlling-plate. Figs. V and VI are bottom plans of the shell with base shown in section andcontrolling-plate in two positions. Figs. VII and IX are elevations of nests of radiating partitions to be arranged in upper mixing ehamber. Fig. VIII is a top plan of Figs. VII and IX. Fig. X is a diagram showing in elevation a desirable means for sustaining the mantle.

In the figures-,1 indicates the base,threaded at 2 to fit the gas-pipe and formed with the gas-inlet 3, diminishing at 4 and provided with the. screw 5 for regulating the supply of gas. This is controlled during burning by a tapering plug or valve 8, provided with a hole.

or groove 9 registering with-the inlet 4, as shown in Fig. II, to permit the gas to pass or turned to cut 0d the gas,as shown in Fig. III, from the main inlet, permitting it to pass through the pilot-light channel. The plug is held in position by plate 10 and screw 11 and may be provided at its outer end 12 with lever 13 and chains 14 14 for controlling or turning off the gas from the flame. It is also formed at its outer end with notch 15, engaging stud 20 on annular controlling-plate 21, supported on shoulder 22 integral with the base and perforated at 23 for the admission of air in the mixing-chamber. The base is threaded at 25 for the attachment of second annular or base plate 26, correspondingly perforated at 27, on which rests a third annular or shell plate 30, correspondingly perforated at 31 and connected to the shell 32 of the mixing-chamber 33, having downwardly-depending margin 34. By turning shell and shellplate 30 on base-plate 26, secured to the base, air-inlet holes 31 and 27 may be arranged to register, admitting a full supply of air, or may be partially closed, admitting only a limited amount,to reduce the-amount ofgasconsumed and expense, the supply during operation being controlled by controlling-plate 21 sim ultaneously with control of gas by the plug, both controlling-plate and plug being operated together from the lever. This shell and mixingchamber are of sufficient size for the admission of a suflicient amount of air and a thorough mixture thereof with the gas and are shown of a convenient conical form, in which is arranged the checker. 36 for slightly checking and confining the air and gas as they enter and to promote their mixture. The flow must be checked only slightly, otherwise the heat and incandescencc would be reduced. In projection 37 in the base, regulated by the screw 38, is the pilot-light channel 39, connected with gas-inlet 3 or 4 below the valve to permit the passage of a limited amount of gas when the main supply is out off to maintain a so-called pilot-1ight for the relightingof the main supply. This pilot-light may be used or not, as desired. From the mixingchamber 33 the mingled air and gas passes through tube 43 to the upper mixing-chamber 44 within cylindrical shell 45, having tube 46 fitted to tube 43 and carrying a gallery 47 for globe or chimney, on which may be supported an incandescent mantle 48 of usual construction. On the top of the shell 45 is arranged a gauze cap to prevent back lighting. In this upper mixing-chamber 44 is preferably inserted a nest 55 or group of radiating partitions 56, called the mixer, and forming between them channels enlarging outwardly, by which intimate mixture of the air and gas is insured, and without checking the draft the mixture is forced outwardly in the channels toward the mantle, where the heat is desired, to generate a high degree of heat adjacent to the mantle and heat it quickly to incandescence. This mixer also absorbs the heat and raises the temperature of the mixture almost to the ignition-point before it escapes through the gauze.

My peculiar construction of base, with independent regulation and simultaneous control of gas-inflow and air, my enlarged conical mixing-chamber, and my radiating mixer arranged in the upper mixing-chamber may be used independently in various sorts of burners, but are preferably combined to obtain excellent combustion with great efficiency and great economy in the use of the gas, to generate a large amount of heat for heating purposes, or, as here shown, to renderincandescent the light-giving mantle.

By my construction of a cone-shaped mixing-chamber with large inlet a considerable amount of air is admitted and immediately mixed with the gas at its inlet, where the gaspressure is the strongest, which produces a good mixture, substantiallyv complete combustion, and great efficiency.

My construction of base is convenient, by which the air and gas are simultaneously controlled and shut off when desired, while still permitting the flow of a minute amount of gas for the pilot-light within the mantle, thus producing a convenient yellow pilotlight instead of the ordinary small blue flame when the air and gas are shut ofi almost entirely. My burner is easily assembled and taken apart to be cleaned.

In Fig. X is shown an elastic and yielding support for the mantle to overcome and counteract the injurious shock and vibration to which it is subjected in many situations. On the base or other support are carried boxes 50, in which are arranged springs 51, acting as a yielding support for guide-plates 52, fitting the boxes and carrying the wire arch 53, from which depends the mantle. The springs absorb all ordinary shocks and vibrations, protecting the mantle and prolonging its life.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
